Examines the ability of infants ranging in age from 21 to 44 hours old to discriminate among visual stimulus arrays. Infants were able to discriminate between small sets of dots (two to three dots) but not between larger sets (four to six). (Author/MP)

Models for developing addition, subtraction, and multiplication with integers are given. (MNS)

An empirical test of alternative claims by Bryant and Piaget concerning the development of invariance of quantities in 3- and 4-year-old children was made. Results support the Piagetian thesis in showing that those subjects respond with stereotypic strategies rather than by an invariance of number principle. (Author/JMB)

Two experiments explored effects of intervention and test conditions on preschoolers' use of counting to compare two sets. At mean age of 4 years 4 months, children in two intervention groups were more likely to use counting to compare sets than those in control group. Use of counting to compare sets was closely related to counting performance.…

Provides guidelines for the appropriate use of tables, their organization and content, and the relationship of tables to text to assist librarians with the presentation of research results and numerical data. (seven references) (Author/CLB)

A series of experiments employing an agreement-error elicitation task allowed the examination of the effects of variations in notional, lexical, and morphophonological features on the implementation of agreement between subject and verb in English. Results show that lexical number seems to dominate verb agreement. (64 references) (CP)

Continues the theme developed in the first paper on this topic which was published in volume 10 of this journal. Carries the historical tale of pi from the late 16th century to the present. (ASK)

Mathematics has had a spiritual aspect throughout its history. Discusses the nature of the interplay between mathematics and spirituality in some traditional and modern contexts. (Contains 29 references.) (ASK)

One minor but irritating problem that most composition teachers face--especially those who handle masses of papers at the high school level--involves coming up with a method of grading that is demonstrably objective but not so rigid that it allows no room for judgment. The author proposes a hybrid grading system: combining numbers and letters. The…

Twenty classes in ten schools with 627 sixth-grade students in five cities in Taiwan participated in this study. The research provides information on the performance differences among written computation, pictorial representation, symbolic representation and number sense. The results of One-way ANOVA analysis indicate that significant difference…

This paper investigates some aspects of number patterns that have been a subject of interest and engaged students of mathematics for many years. It is left for the teacher to select and fashion any aspects they feel suit their own students.

Five-year-old children categorized as skilled versus unskilled counters were given verbal estimation and number word comprehension tasks with numerosities 20-120. Skilled counters showed a linear relation between number words and nonsymbolic numerosities. Unskilled counters showed the same linear relation for smaller numbers to which they could…

Prediction is a great skill to have in any walk of life: it can, in fact, save lives at times. While the two investigations posed in this column may not be that dramatic, they might just increase one's appreciation of some important connections between grids and rectangles and the divisors of numbers that appear in the dimensions of those…
